MATERIAL-HANDLING- DEVICE.

Application filed February This invention has relation to material handling devices adapted for discharging and conveying solid material by gravity from an elevated positioninto a conveyance such as a boat, car or truck, positioned adjacent thereto and which is to be loaded with such material. Not. only is the device of the present invention provided with mechanism by meansof which it may be raised or lowered to permit the discharge of the material .into conveyances of various heights and located at variouselevations, and with means for varying the angle of chute and for raising the free end of the chute into inoperative position, but the chutev is mounted so as to be capable of being swung laterally to traverse a considerable lateral angle of discharge at the various elevations.

More particularly, the device of the present invention is applicable for use at docks and wharves for loading lighters and freighters. Thus not only is the device of the present invention adjustable to allow the discharge of material into the hatch of a boa-t regardless of variations of the tide, but

' hereinafter be described in conjunction with the accompany ng drawings, where1n- Fig. 1 represents in front elevation a de vice embodyingthe present invention;

Fig. 2 represents aside elevation of the same partly in section;

Fig. 3 is a detail section of the device on the line 3-3 of Fig. 2, as seen by an observer facing the right hand side of the sheet;

Fig. 4 is a detail perspective with certain parts broken away, showing the mounting of the chute which permits the vertical adjustment thereof;

Fig. 5 is a section on the line 5--5 of Fig. 4, showing in detail the lateral swingable mounting of the chute.

While the device of the present invention will be described in connection with the handling of logs cut up into two to four foot 9, 1926. Serial No. 87,139.

lengths, and especially suitable for pulp manufacture, it is obvious that this application of' the device is illustrative only and that the device may be utilized for loading other solid materials by gravity into a conveyance positoned adjacent thereto.

Referring to the drawings,1 represents a platform which is erected on piers 2 at the water front, and onto which the logs are dis charged from a sluice or conveyor, not shown. The platform is provided with partitions 8 at either side for guiding the logs into a well or shaft 4, which constitutes an enclosure for guiding the material to the chute. The wellcomprises the side walls 5, 5 and the rear wall 6, all of which may be constructed of wood and reinforced on their nner faces with boiler plate 5, for example. The side walls 5, 5 serve as supports for channel or guide irons 60, which constitute part of the vertically adjustable mounting for a receiving hopper 10 and a chute 11. The side walls 5, 5 may be stayed by braces 7 and 8. A hunter plate 9 con stitutes the front wall of the well 4 and also serves as a support for the hopper 10 and the chute 11, into which the hopper discharges. The hopper is arranged to receive the material discharged from the well and is secured at both its sides 10 10, to bars 12 and 13, which are in turn carried by the hunter plate, as will hereinafter be described. The bars 12 and 13 are secured to each other at their lower ends by a pair of spaced cross bars 14, 15, through which passes a bolt 16 which serves as a swingable mounting for the chute 11.

To allow an adjustment of the angle of chute and the raising of the chute into upstanding inoperative position, as shown in dot-ted outline in Fig. 2, the chute 11 comprises a relatively short upper section 11a, the lower side walls 6 of which are provided with pins to which the side walls 0 of the lower relatively long chute section l1 are pivotally secured. The lower end portion of the chute isprovided with a lifting bracket 17 having arms 17 pivotally secured to the walls 6 and provided with a lifting hook 18, to which is attached a cable 19. The cable passes over sheaves 20 and 21 to a Windlass 22, which may be driven by a motor 23 or other suitable driving means. By the operation of the Windlass, the chute may chute.

thus be swung between extended operative and upstanding inoperative positions.

The laterally swingable mounting of the chute section ll is afforded by means of an upper and lower bracket 25 and 26 secured thereto and through which the pivot bolt 16 passes. These brackets are maintained in spaced relationship by means of an intermediate sleeve 27 loosely mounted on the bolt 12 and forming part of a bracket 25 securedto the chute section 11. The upper side walls of the section 11 are upwardly diverging and are separated from one another a distance somewhat greater than the side walls g, g of the hopper 10 depending therein soas to permit the lateral swinging .to either side of the lower section 11 of the chute to permit an operator on the dock to adjust the lateral angle of chute.

As previously stated, means are also provided for raising or lowering the chute as desired with the variation in tide, from the extended position in dotted outline to its ex tended position in full lines, as shown in Fi 2. To this end rollers 29, 29, guided by the channel irons 60, are secured to stud shafts 30, 30, which pass through the bars 12 and 13 and are journaled in bearings provided by the brackets 31 and 81", which are fastened to angle irons 82, 32" on the hunter plate. A pulley 34 is secured to the upper end of the bunter plate, about which is engaged a cable 35 passing over the pulley36 and thence to a windlass 37, which may be driven by a motor 38 or other suitable means. To facilitate the raising of the hunter plate and chute supported thereby, as well as to steady the lowering thereof and to steady it when it is arranged to discharge at any given elevation, both sides of the bunter plate are provided with hooks so, to each of which is secureda rope or cable 41 passing over guide wheels 12, 42, and thence downwardly, and having a counterweight 4-3 of suitable mass attached thereto at its end. By operating the windlass 38, the bunter plate and the chute supported thereby may be raised or lowered to the desired elevation. When it is in its lowermost position, the cross bar 14:

rests on a sill 45, which is bolted down to the flooring 46 which supports the platform 1.

lVhile the description of the present invention has been confined to a more or less preferred embodiment thereof, it should be obvious that this'is by the way of example only and that various changes and modifications may be made therein without departing from its spirit or scope as defined by the appended claims.

lVhat I claim is:

1. A device for loading material by gravity into a conveyance positioned adjacent thereto, comprising a shaft having a wall which constitutes a bunter plate, a hopper supported bv said bunter plate and arranged to receive the material discharged from said shaft, a laterally swingable chute into which said material is fed from said hopper and supported by said bunter plate, and means for raising and lowering said bunter plate.

2. A device for loading material by gravity into a conveyance positioned adjacent thereto, comprising a shaft having a wall which constitutes a hunter plate, a hopper supported bv said bunter plate and arranged to receive material discharged from said shaft, a chute into which the material falls from said hopper comprising a short upper section and a lower section swingable in ,a vertical direction secured thereto, means for swinging said lower section about said upper section, a pivot supported .by said bunter plate and about which said chute islaterally swingable, and means for raising and lowering saidbunter plate.

A device for loading material by gravity into a conveyance positioned adjacent thereto, comprising a shaft having a wall which constitutes a hunter plate, a hopper supported by said bunter plate and arranged to receive material discharged from said shaft, a laterally swingable chute into which said hopper depends comprising a short upper section having its side walls separated a sulhcient distance to permit the lateral swinging of the chute but without interruptmg the continuity of hopper and chute, and a lower section swingable in a yertical direction about said upper section, means for swinging said lower section about said upper section, a pivot supported by said bunter plate and about which said chute is laterallyswingable, and means for raising and lowering said bunter plate.

In testimony whereof I have affixed my signature.
